Catalytic converters are commonly used exhaust emission control devices that reduce harmful emissions from internal combustion engines. It is also referred to as a catalyst or a scrubber. It assists in the conversion of toxic combustion byproducts (coppers, lead, etc.) into harmless carbon dioxide, oxygen, nitrogen, and water. The engine’s performance is improved through the catalytic converter which reduces harmful emissions from the exhaust system for fuel.
Most cars have catalytic converters which reduce harmful emissions from the engine. These harmful emissions include hydrocarbons, sulfur oxide and carbon monoxide. These emissions impact the performance of the vehicle and can even cause harm to the driver. Diesel engines emit more carbon monoxide than other engines.
There are two types of catalytic converters that are direct air injection and an oxygenizer-based system. Direct air injection occurs when gases like argon are injected directly into the combustion chamber to create oxygen. The catalyst is then activated by the oxygen present in the chamber. The catalyst activated particles combine with other emissions in the air stream and adhere to them resulting in the production of nitrogen, carbon dioxide, and water as a byproduct.
The oxidizer-based system utilizes catalytic converters for an oxidation system in the exhaust system. Catalytic converters convert dangerous exhausts from internal combustion engines into harmless substances such as water, nitrogen, or carbon dioxide. They can be utilized by a range of vehicles, both light and heavy, to increase fuel efficiency and reduce emissions. Some heavy duty vehicles, like forklifts and mobile crane trucks, that have exhaust systems, might also require catalytic converters in order to comply with emission standards established by state regulatory agencies.
Catalytic converters are employed in injection systems to block combustion gases from exiting the engine compartment. Three-way catalytic converters use a stoichiometric point to determine the amount of time a particular chemical will remain active without being destroyed by the external emissions. Each three-way system differs in a small way, but all work on the same general principle.
The United States has regulations for catalytic converters. They must comply with certain emission standards. Many manufacturers also sell vehicles that are equipped with federal conformity kits, which include catalytic converters. To ensure conformity to DOT emissions standards, these kits have to be approved and certified by the United States Environmental Protection Agency.
There are many kinds of catalytic converters. A two-handle electrochemical catalytic converter washcoat, that includes binder and an oxygen catalyst, is among the most popular. The binder will bind with any pollutants and let them be removed from the emission stream before they reach the catalytic converter. A core cleaner is used to cleanse the catalyst of any remaining dust and other debris. A majority of these systems have the flow control valve which shuts off the unit when it is functional. However, some systems will shut down the unit once the washcoat has been emptied or after a set time.
The final catalytic converter used in automobiles is the x reduction catalyst. This type of converter uses only one catalyst instead two. Instead of allowing only one type of pollutant to harm the catalytic converter, it splits the gas molecules that are polluted into smaller, more easily combustable particles. Catalytic converters that reduce X are also available in residential applications, which use an additional catalyst for oxidation and are eco-friendly.
